In the slow block to polyspermy, sperm penetration releases an inflow of Ca2+, which in turn stimulates the cortical reaction.
<h3>What is cortical reaction?</h3>
- A medium known as the cortical response, which is started after fertilization, stops polyspermy, or the union of several sperm with one egg.
- The cortical response, which in numerous species serves as the top element of the slow block of polyspermy, gradationally forms a endless hedge to sperm entry in discrepancy to the rapid-fire block of polyspermy, which instantly but temporarily inhibits new sperm from fertilizing the egg.
- This barrier is made up of the egg's plasma membrane and cortical granules, specialized secretory vesicles found in the cortex (behind the plasma membrane) of the egg.
<h3>What follows the cortical response?</h3>
- Cortical granules (CG), a type of specific organelle in the egg, release their contents into the perivitelline region after sperm and egg fuse (cortical response), making the zona pellucida resistant to sperm adherence and penetration.
